To all whom t 'may concern.'

Be it. known that I, ALviN L. COX, citizen of the United States,residing at Elizabethtown, in the county of Hardin and State ofKentucky, haveinvented certain new and useful Improvements inDoor-Fasteners, of which the following is a specification.

My invention relates to door fasteners, and the object thereof is toprovide asimple and inexpensive device, which, in its operation,'

direction, corresponding tothe opening of the door, and with a lockingmember to lprevent rotation thereof and maintain it in engagement withthe keeper.

In the accompanying drawings, illustrating my invention, and forming apart of this specification, and wherein like numerals are used todesignate like parts throughout the several figures, Figure 1 is anelevation of a portion of a door and the casing, illustrating myimproved fastener applied thereto. Fig. 2 is a horizontal sectional viewtaken therethrough. Fig. 3 1s a pcrspeotlve elevation of the fasteningmember', and, Fig. 4 is a horizontal sectional view through a portion ofa door, and a fastener attached thereto, and -forming a slightlymodified form of my invention.

In the embodiment of my invention, as illustrated in Figs. l and 2, Iprovide the easing A, of a door B, with a keeper l, at`

tached vertically upon the casing strip-C, against which the outer edgeof the door B abuts when the sameis closed. The keeper l is of theU-shaped form, having its ends secured to the strip C whereby to holdits body portion spaced therefrom. Mounted upon the inner surface of thedoor B, is a rectangular frame 2, open at its side facing the verticaledge of the door, and provided with a transverse pin 3, upon which ismounted an operating member 4, extending,

outwardly through the open side of said casing, and provided with a cutout portion forming the keeper engaging fingers 5 and 6 upon each sidethereof, and adapted to receive the keeper l therein when the door B isclosed as' shown in Fig. 2. The casing 2 is provided with a transversepin 7 rearwardly of the pin Blupon which the operating member 4 isrotatable, upon which pin 7 is coiled a spring 8 having one end thereofbearing upon the inner surface. of one wall of said easing and havingits opposite end bearing against the rear cam,` edge 9, of

vsaid operating member 4, which edge 9, as

shown in Fig. 3, is provided with a central slot l0, to preventaccidental displacement of the end of spring 8 bearing thereupon. Thusupon the movement of the door keeper from the closed position shown inFig. 2, the operating member t is rotated upon the pin 3, by contactbetween the keeper l and the engaging linger 5 thereof, against thesteady tension of the spring' 8, whereby the door is prevented' fromaccidental opening. The opposite movement, to close the door, finds theoperating member 4 in the position shown in dotted lines in Fig. 2,owing to the rotation thereof during the openino' movement, and uponengagement of the keeper l with finger 6, the rotative movement 'of saidmember is much quicker than the rotative movement thereof when the dooris open, inasmuch as the same is locked against the tension'of spring 8.The rar cam edge of. the operating men'lber 4 is provided with avV-shaped eut out portion l1, which is adapted for the reception thereinof a portion of a locking member 12, pivotally mounted upon a transversepin 13, within the Casin .2, and extending through a slot 14 in the wallthereof, in order that the same may be pressed into engagement with thesaid out out portion .ll,'-"\fvhen the member 4 is in engagement withthe keeper l, as shown in Fig. 2, to prevent movement thereof and lockthe same and the door B. In this form of my invention, the rotativemovement of the operating member l is limited in both directions, bymeans of a strip l5, arranged transversely between the walls of thecasing 2, and parallel with the pin 3.

In the form of my invention illustrated in Fig. 4, the rear cam edge ofthe operating member 4 is provided with a central slot, somewhat deeperthan the slot l0, to guide the engaging end of spring S, in the formshown in Figs. 1 and 3, and is further lrovided with a transverse pin16, exten ing .through the said slot, and is adapted for a swinginglocking member for engagement n within said cut out portion in oneposition of said rotative member to lock the same from rotativemovement, substantially as described.

2. In a door fastener of the character described, a rotative operatingmember, and a sprintf member controlling rotative movement oisaidrotative member and constitut- 1n@ a stop to limit such movement,substantiflly as described. V

In testimony whereof I aflix my signature in presence of two witnesses.
